Application filed November 5, 1919.

To all whom it may concern:

Be it known that I, SAMUEL H.-FURRY, a citizen of the Unitedsstatesesiding at Lancaster, in the county of F airfield and State of Ohio,have invented certain new and useful Improvements in Road-Crossings, ofwhich the following is a specification.

This invention relates to improvements in track crossings and moreparticularly to railroad crossing construction embodying means forbridging the ties and aflording an efiicient and exceptionably durableroad bed at railway crossing points, thereby eliminating the usualjolting of a vehicle moving thereover and also reducing the pull ordraft to a minimum by reason of the gradual and even grade afforded andthe elimination of prominent places or obstructions in the road lleretofore in the usual construction of concrete asphalt or woodcrossings the ties of the railroad have usually been utilized to retainthe structural elements of the crossing in position with the result thatnot only is the resiliency of the ties impaired but the continuousvibration eflected by the rolling stock ultimately injures and destroysthe construction of the crossing, being transferred directly thereto.The present invention has for its purpose the provision of a crossingand approach thereto which will bridge the ties and consequentlyeliminate these disadvantages and furthermore the invention contemplatesthe construction of a reinforced crossing and approach which will beexceedingly durable and unlikely to become fractured or broken due tothe jar or vibration set up by passing vehicles or trains.

Moreover the vibration effected by the rolling stock upon adjacentportions of the crossing has heretofore tended to disintegrate theplastic construction thereof and to this end auxiliary reinforcing meansof an improved nature have been lncorporated in the present inventionparticularly at the edges of the crossing ad acent the ties.

Furthermore, the improvements in bridge a proaches as set forth in myprior Patent 0. 1,300,949, April 15, 1919 have beenincorporated with thepresent invention .to

form a unitary structure therewith affording an efficient and durableapproach to the crossing which may be readily constructed at nominalcost.

With these and other objects in view the invention comprises the novelfeatures of construction, combination of elements and arrangement ofparts which will be more fully described in the following specificationand set forth with particularity in the claims appended hereto.

Figure 1 represents a plan view of the road crossing constructed inaccordance with the invention.

:Fig. 2 represents a longitudinal sectional View along the road Way,taken transversely of the railway track.

Fig. 3 represents an enlarged fragmentary sectional view at right anglesto Fig. 2.

Fig. 4 represents an enlarged fragmentary sectional view in the plane ofFig. 2 illustrating a modification of the invention.

Fig. 5 represents a fra mentary sectional view at right angles to Fig.4: of the modification.

Referring more particularly to the drawings, a portion of the rise 1 ofan approach tothe crossing 2 at the left side of F ig. 1 is filled witha plastic material the-lower end of which is provided with a pocket orgutter 3 to provide a drain extending transversely 1 of the road andinto which gravel or loose rock 4 is placed, for an obvious purpose. I

desire that it be understood that the construction of the rise orapproach constitutes the subject matter of my previous-patent abovereferred to and is merely shown here with by wayof illustration tobringout more clearly the cooperation between the prior patent and thepresent structure. Although in the present drawings, the plasticmaterial of the approach 1 is shown as exposed to wear, it will bereadily understood that a metallic covering also provided withcor'r'ungxto those illustrated in,

fgations correspondi the accompanying aw-ings may be applied to thesurface of the roadway, when found desirable or necessary. Whether-theroad is faced or covered with corrugated metal or not is clearlyoptional and such variations may be resorted'to as necessity orpreference may dictate. The corrugations, however, are extremelydesirable particularly in the peculiar V-shape illustrated in Fig. 1 asdue to their utilization thedurability and efiiciency of the approach 1smaterially enhanced.

The railroad in connection with which the present invention is primarilydesigned for use embodies the usual ties A upon which are arranged therails B, the latter bein properly mounted upon the railroad bed moreclearly shown in Fig. 3.

The crossing per se consists essentially of three parts or sections, thetwo end outer sections 7 and the center section 8. The outer or endsections are arranged outwardly of the track rails B whereas the centerpart or section 8 is interposed between the track rails, adequate spacebeing provided between the track rails and the sections of the crossingto accommodate the flanges of the wheels of the rolling stock and alsoto prevent communication of the ,vibratory movement of the railsincident to the passage of trains thereover to the structure of thecrossing and thereby preventing possibility of consequent injury to thestructure of the crossing due to the disintegrating effect of suchvibratory movement.

Each section of the crossing is preferably formed in a plurality ofparts or dlVlSlOIlS, each part or division preferably being of suchwidth to overlie two of the rallroad ties A, as suggested in Fig. 3, andtheir parts being separated or insulated from each other by asphalt orother yieldable materlal 10.

Metallic reinforcing elements 16 are ap-' plied to the edges of thecrossing sections 7 and 8 at points adjacent the track rails to preventpremature wear of these port1ons of the crossing incident to the wearingeffect of vehicles passin thereover and the space between the reinorcing elements and the crossing sections and the rails B is filled withasphalt or, other resilient materlal 16' to prevent water from findlng1ts way beneath the crossing and havin a detrimental effect upon therailroad bed The center section 8 is supported, at points intermediatethe ties A directly upon the railroad bed C and is maintained 1n spacedrelation to the ties A by supporting Reinforcing bars 13' and 17 arepreferably anchored in the plastic material of the crossing to increasethe strength and rigidity thereof and to bind together the several partsof each section. The end outer sections of the crossing which aredisposed outwardly of the track rails B are supported upon the arches 11which latter are main tained in arched condition during the construction of the crossing by retaining members 20 as illustrated in Fig.3.

Referring to the modification of the invention illustrated in Figs. 4and 5 the letter A designates the bed oftherailroad, which in thisinstance is built up between the ties 30 to a height slightly above thelatter to provide an adequate support for the spacing members orsupports 31' which are formed with corrugated upper portions 32receiving and supporting a sectional corrugated covering 33 preferablyformed of metal and having the terminals extended in spaced relationbelow the heads of the rails 34 to provide a space for the reception ofthe flanges of the wheels of the rolling stock. The supporting members31 are arranged intermediate the track rails 34 and additionalsupporting members 35 are arranged outwardly of the track rails andsupport the corrugated metallic plates 36 which are extended intoproximity with the approaches toflthe crossing (not shown) in Figs. 4and 5. For the protection of the railroad bed against the deterioratingeflect of water, resilient fillers 37 are arranged between the terminalsof the supports 31 and 35 and the rails 34. In this form of theinvention the crossing is provided with a metallic covering which, incertain instances is extremely desirable and although nometalliccovering is shown as applied to the type of inventionillustrated in Fig. 2, it will be understood that such covering may bereadily applied thereto when necessary or desirable.

The covering plates 33 and 36 are preferably formed in" convenientlyremovable sections and have yieldably cushioning elements 33 interposedbetween the sections, as suggested in Fig. 4. At the right of Fig. 2 isshown a channeled connecting member 40 for joining an approach 41constructed of brick or similar material with the outer section 7 of thecrossing,

It is thought that the construction and purpose of the present inventionis obvious from the above description and I shall dwell.

no further upon it; however I desire tocall particular attention to boththe utilization of asphalt or plastic material as a cushioning mediumand the fact that no portion of the crossing touches the ties, thuspreventing impairment of the resiliency of the ties and disintegratingeffect of the vibration of a portion of the crossing should the latterbe subjected to the vibratory-movement of the track rails and tiesincident to the passage of trains thereover.

I do not limit my invention to the specific structural details hereindescribed and illustrated but desire that it be understood that variouschanges and modifications may be made therein Which come within thescope of the appended claims.

lVhat I claim is:

1. A road crossing for railways constructed and arranged to lie inspaced relation to the track rails and ties to prevent transmission ofthe vibratory movement of said rails and ties to the crossing.

2. A road crossing for railways constructed and arranged to lie inspaced relation to the track rails and ties to prevent transmission ofthe vibratory movement of the rails and ties incident to the passage ofa train thereover to the crossing, and approaches arranged laterally ofthe road crossing.

3. A road crossing for railways having corrugations and constructed andarranged to lie in spaced relation to the track rails and ties topreventtransmission of the vibratory movement of the rails and ties tothe crossing.

4. A road crossing for railways having transverse corrugations andconstructed to lie in spaced relation to the track rails and ties toprevent transmission of the vibratory movement of the rails and ties tothe crossing.

5. A road crossing for railways constructed and arranged to lie inspaced relation to the track rails and ties, and resilient cushioningmeans adapted to be interposed between the track rails and the crossing.

6. A road crossing for railroads constructed and arranged to lie inspaced relation to the track railsand ties to prevent vibratory movementof the latter from being transmitted to the. crossing, and resilient'cushioning means interposed between the track rails and the crossing.

7. A road crossing for'railways composed of a plurality of sections, andmeans to support the sections of the crossing in spaced relation to thetrack rails and ties.

8. A road crossing for railroads comprising a road structure, means tosupport the road structure independently of the track rails and ties,and resilient cushioning means adapted tobe interposed between. parts ofthe railway and road structure.

9. A road crossingforrailroads comprising a road structure, and means tosupport the road structure independently of the ties of the railway atpoints intermediate said tles.

10. A road crossing for railways comprising a road structure consistingof a plurality of sections, means to support the sections of "the roadstructure independently of the track rails and ties, and resilientcushioning means interposed between the sections of the road structureand'adapted to maintain said sections in spaced relation to parts of therailway.

In testimony whereof I afiix my signature hereto.
